Sorry to hear about your sinuses... =( I can relate.... =S The bow part of violin is the trickiest part, but I think the instrument is more musically logical than a lot of other instruments. I don't think I could have ever passed a music theory class if I had learned a different instrument....it only made sense because I could whip out an imaginary violin during exams and relate things to how the violin worked...xDI had terrible sinuses (still do!) and flute was really my only option apart from a hand only instrument haha. I would love violin to be honest! I watch a few other channels who do epic gaming music with violins and it just sounds so very awesome. It is a really cool instrument
And it's never too late to learn a new instrument! : D
